I'm modeling after the [Hirst Arts Gloomhaven](http://www.hirstarts.com/gloom/gloom.html) approach. These are shorter than what Hirst is doing, more along the lines of a Wyloch/TrueTiles style of walls, but uneven.

Updates:
* 6/19/2018 - Added some "bare" versions that just have the ground texture, as requested.
* 6/10/2018 - Added a second 3-hex tile.
* 5/24/2018 - Added another 2-hex; this one has a couple of spots to fit Curufin's [small barrels](https://www.thingiverse.com/thing:1477280). I'd just glue them after painting.
* 5/21/2018 - Added another 1-hex, 2-hex, and 4-hex wall.
